Once a tolerance is established, the residue level in the tolerance is the trigger for enforcement actions.

Today, the agency said information since then has shown that the residue levels on some crops indicated captan posed only a negligible risk.

While the agricultural areas did not show intense pollution, the former pesticide storage site contained residue levels that were considerably greater.

This will not suffice for higher dimensional local fields, since one needs to take into account the topology at the residue level too.

Fifteen minutes later they were far enough away so that radioactive and chemical weapon residue levels disappeared.

The residue level in the body was never more than 1.5% in monkeys.

The highest residue levels come from pesticides used on the surface of fruit, vegetables and cereals.

If these arbitrary and toxicologically unjustified residue levels were observed, fruit and vegetables could no longer be produced by conventional means.

Under this system, the residue levels are precautionary levels, not danger levels for the consumer.

In 1985, after reviewing new animal studies and making assumptions about residue levels in food, the agency proposed to ban the fungicide.
